EN41B/905M39 Alloy Steel
EN41B/905M39 Alloy Steel manufacturers and suppliers,supplied with round rods,square/flat bars,rollers,shafts,blocks and forging pieces.
As a chromium aluminium molybdenum steel EN41B is usually supplied in the hardened and tempered condition. Properties of the steel combine high wear resistance together with toughness and ductility. It is defined by its suitability for nitriding from which 905M39 can give a hard wear resistant case up to 68HRc.Suitable for applications requiring excellent resistance to wear and abrasion. Typical applications include connecting rods, small extruders, valve stems, Injection Moulding Equipment, Hydraulic Cylinders, Gears And Pinions, Die Inserts, Valve And Gate Parts, Cams, Piston Pins, etc. 905M39 steel is widely used in the automotive, textile and general engineering industries. With its resistance to wear 905M39 is used in other applications such as brick press plates, clutch plates, gudgeon, track and shackle pins.

|Tensile strength||Yield strength||Elongation||Hardness|
Hardening is used to meet specific mechanical properties which can make the material fit for use.
Tempering is used to remove the stresses and brittleness caused by quenching, develop the required mechanical properties,and improve dimensional stability and toughness.
Annealing is a process used to soften the material,enhance the machinability and toughness,increase the ductility and improve the homogeneity in material.
Normalizing is used to make material softer , refine the grain size and improve the uniformity of microstructure and properties.
